crashdc

NAME

crashdc - Diagnostic data collection for a running or crashed system

SYNOPSIS

/usr/bin/crashdc [system-kernel] [core-image]

DESCRIPTION

The crashdc utility examines the core image of the operating system to
extract critical diagnostic data. This utility is a shell script that
invokes several tools and commands that extract selected parameters of a
running or a crashed system (for example, system configuration, running
processes, and panic messages).

The arguments to the crashdc utility are the system kernel and the
core image. The default values are /vmunix and /dev/mem,
respectively. If you specify no arguments, the crashdc utility examines
the running system.

The system usually invokes the crashdc utility during system startup. If the
most recent core dump has been saved by the savecore command, both the
core image and the system kernel (respectively vmcore.n and
vmunix.n, where the variable n is the crash number) are saved
in the crash directory (by default, /var/adm/crash). Also, the crashdc
utility saves the output as the file crash-data.n (where the variable
n is the crash number) in the crash
directory. The crashdc utility is invoked only if crash-data.n
output in the crash directory does not exist or is not from the most recent
crash.
